Burleson Energy (ASX: BUR) has identified the potential source of excess water produced during flow back of its first horizontal development well at the Heintschel gas condensate field, Texas.
While two spinner surveys run in the Truchard-2H well both suffered failures of the spinner tool, ancillary temperature information was recorded in the first run indicated that frac slot 6, the closest to the vertical section, could be producing water at abnormally high rates.
The company now plans to set a retrievable packer below frac sleeve 6 and test flow from frac slots 1 to 5 through production tubing, while waiting to see if recorded spinner data can be recovered from the first spinner tool.
If this results in a reduction in water flow relative to gas flow, then Burleson may either remediate frac sleeve 6 or close it and produce from the bottom 5 frac sleeves.
This work is expected to be completed within the next week. The cost of the work will be about $120,000, of which half is already accounted for in the original well budget.
Prior to the start of this remedial work, the Truchard-2H had flowed at a restricted rate of 1.5 million cubic feet of gas and 70 barrels of condensate into the gas sales line.
The flow included 1,400 barrels of water per day, which is a manageable level with current lease equipment,
